We can all stop obsessing over a ratty piece of photocopied paper now. The official Lollapalooza 2012 lineup has been announced, and here it is. If you wanted a monster list of must-see bands as well as a few lesser-knowns you've been hearing buzz about, your wish is our command.

Does this affect whether or not you'll attend the fest? Are you a die-hard Lolla fan who will be there no matter what, or are you on the fence, now that you know? For us, we've seen enough to know we won't miss this year's rumble in Grant Park. And yes, that mean you can rest assured that we'll be bringing our street-style snapping cameras with us. But at long last, we can finally stop wondering, and start getting excited. The hard part, now? Waiting for August. (Lollapalooza)
